A 4D baby scan is a particular type of scan conducted to measure the growth of a baby. Through 4D technology, the baby can be seen in a four dimensional view and prospective mothers can also see a baby's movement inside womb.All types of baby scans, including 4D and 3D scans use the same ultrasound procedure, however the people carrying out the procedure can vary in terms of experience. The best baby scan companies employ midwives to train and become qualified sonographers as they understand the pregnancy cycle the best. 4D Scans are popular amongst expectant mothers because they pose no health risk to unborn babies, due to the sound wave nature of the technology. When an expectant mother reaches 24 - 32 weeks gestation, a scan can be conducted to see the health of the baby and also what the baby looks like.By this point a baby's body parts are fully developed and the sonographer can take a clearer view of the baby inside the womb. Through the scanning process, fetal anomalies can also be recognised and addressed with the mother, however this is a small consideration that expectant mothers have when choosing to have a 4D scan. The majority of pregnant mothers have a 4D scan so that they can see their baby and its habits in the womb.Most couples get excited as pregnancy progresses and anticipate the coming of the baby; but more excited is the expectant mom who already wants to see the baby for herself. Thanks to 4D scanning technology, expectant mothers can start to monitor the growth of their baby even before birth takes place. thanks to 4D scan and 3D scans Article Source: http://EzineArticles.com/?expert=Amo_SinghAdditional Helpful Resources:
